TECHNICAL FIELD

The present invention relates to an improvement of a column base frame which is used for forming a column base for supporting a column during construction of a building.

BACKGROUND ART

A conventional column base frame has been manufactured by a method of pouring synthetic resin into a constantly-shaped molding frame and hardening the resin. For a column base serving as a base of a column, it is necessary to manufacture the column base frames of large and small sizes in accordance with the size of the column. Thus, there is a need for forming the column bases of large and small sizes in response to the size of the column, which causes the large and small column base frames to be individually manufactured.

However, the conventional column base frame has the following shortcomings.

Firstly, since the column base frame integrally manufactured by the molding frame, such as the conventional column base frame for forming the column base for supporting a piping or the like, is formed into a constant shape, the column base frame is bulky during carrying it. This causes a carrying cost to be too expensive.

Secondly, the column base frame is integrally formed into a predetermined shape. Therefore, if an attempt is made to mount the column base frame to the column base for supporting an iron column for supporting the piping in order to more tightly support the iron column, the column base frame cannot be mounted to the column base.

Thirdly, in case of the column base frame for forming the column base of the column for supporting the piping and the column base frame for forming the column base for supporting the iron column or the like, if the attempt is made to increase the size of the column base, the column base frame itself cannot be increased in size, that is, increased in number. Therefore, the conventional old column base cannot be reinforced.

Fourthly, when fresh concrete is poured into the column base frame, the column base frame is disadvantageously deformed due to a weight of the fresh concrete.

It is therefore an object of the present invention to provide a column base frame with an opening prevention tool which is not bulky during carrying it by an assembled column base frame, can be mounted to the base of the column for supporting the piping, can be increased in number, can be easily assembled, and is not deformed even if the fresh concrete is poured into the column base frame.

DISCLOSURE OF THE INVENTION

According to one aspect of the present invention, there is disclosed a column base frame with an opening prevention tool, wherein the opening prevention tool is mounted between the protruding plates of the column base frame assembled by connecting L-shaped corner frames, each comprising fitting holes and cylindrical fitting holes on one end thereof; movable protrusions, inserting protrusions and cylindrical protrusions on the other end thereof; and protruding plates through which through holes are bored.

According to another aspect of the present invention, there is disclosed a column base frame with an opening prevention tool, wherein the opening prevention tool is mounted between the protruding plates, through which the through holes are bored, of the column base frame assembled by connecting increased frames to L-shaped corner frames, the L-shaped corner frame comprising fitting holes and cylindrical fitting holes on one end thereof; and movable protrusions, inserting protrusions and cylindrical protrusions on the other end thereof, and the increased frame comprising fitting holes and cylindrical fitting holes on one end thereof; movable protrusions, inserting protrusions and cylindrical protrusions on the other end thereof; and protruding plates through which through holes are bored.

BEST MODE FOR CARRYING OUT THE INVENTION

The present invention will be described below with reference to the accompanying drawings.

FIG. 1 is an elevational view of a column base frame with an opening prevention tool according to the present invention. FIG. 2 is a plan view of the column base frame with the opening prevention tool according to the present invention.

As shown in FIGS. 1 and 2, a column base frame 1 with an opening prevention tool of the present invention is assembled by preparing four corner frames 2 shown in FIGS. 3-6 and connecting the four corner frames 2, 2, 2, 2, and a plurality of opening prevention tools 20, 20 are mounted in the assembled column base frame 1 with the opening prevention tool. Numeral 4 denotes a connecting portion of the corner frames 2 and 2. Of course, the column base frame 1 may have a structure in which the prevention tools 20, 20 are not mounted therein.

FIGS. 3 and 4 show the corner frame constituting the present invention. In the first place, FIG. 3 is an elevational view of the corner frame constituting the column base frame with the opening prevention tool according to the present invention. FIG. 4 is a left side view of the corner frame 2 constituting the column base frame according to the present invention.

A plurality of fitting holes 8-8m are formed in a fitting formation portion 8 on the right end of the corner frame 2 shown in FIGS. 3 and 4. A plurality of movable protrusions 6-6d, inserting protrusions 7-7g and cylindrical protrusions 9-9b are formed on the left end of the corner frame 2. One surface of the end of each of the movable protrusions 6-6d is formed into an arrowhead shape so that, when it is fitted into the other corner frame 2, it may be engaged with and may not be removed from the other corner frame 2.

Numerals 11-11b denote horizontal protruding bars. These horizontal protruding bars 11-11b are used for reinforcing a strength of the corner frame 2. Numeral 14 denotes vertical protruding bars. These vertical protruding bars 14 are used for increasing the strength of the corner frame 2. It should be noted that the horizontal protruding bars 11-11b and the vertical protruding bars 14 may not be provided.

Numeral 11c denotes protruding plates. Numeral 11d denotes through holes. The protruding plates 11c are used for preventing the column base frame from rising due to a pressure and a weight of fresh concrete when the fresh concrete is filled into the assembled column base frame. The through holes 11d are used for preventing the column base frame from rising by passing bolts therethrough and driving the bolts into the ground and for inserting the opening prevention tools 20 and opening prevention bands 21 thereinto. It should be noted that the protruding plates 11c and the through holes 11d for passing the bolts therethrough may not be provided as required.

Numerals 7i, 7i, 7i, . . . denote fitting protruding bars. These fitting protruding bars 7i, 7i, 7i, 7i, . . . are used for making the fitting more tight when the inserting protrusions 7-7h are inserted/fitted into the fitting holes 8a-8m during the assembly. Vertical protrusions may be also disposed in the similar positions on the rear surfaces of the inserting protrusions 7-7h or on the ends of the inserting protrusions 7-7h. Of course, no protrusions may be disposed on the front and rear surfaces of the inserting protrusions 7-7h.

FIG. 5 is a plan view of the corner frame constituting the column base frame with the opening prevention tool according to the present invention. FIG. 6 is a bottom view of the corner frame constituting the column base frame with the opening prevention tool according to the present invention. As shown in FIGS. 5 and 6, the corner frame 2 is curved so that it may be generally L-shaped. The four corner frames 2 of the same shape and the same size are connected to each other, whereby a single column base frame 1 with the opening prevention tool shown in FIGS. 1 and 2 is completed.

Numeral 6e in FIG. 6 denotes a step. Due to this step, when the corner frames 2, 2, 2, 2 are connected to each other so as to be assembled, the corner frames are completely bonded to each other. Therefore, the fresh concrete poured into the column base frame 1 with the opening prevention tool is not leaked outwardly from the column base frame 1.

In order to connect the corner frames 2 and 2, the movable protrusions 6-6d and the inserting protrusions 7-7h are fitted into the fitting holes 8a-8m formed in the fitting formation portion 8 on the right end and the cylindrical protrusions 9-9b are also fitted into cylindrical fitting holes 10-10b, whereby a generally conical column base frame 1 as shown in FIG. 1 is completed.

FIGS. 7, 8 and 9 show an increased frame to be connected to the column base frame when the increased frame is added to the column base frame with the opening prevention tool according to the present invention. FIG. 7 is an elevational view of the increased frame. FIG. 8 is a right side view of the increased frame. FIG. 9 is a left side view of the increased frame.

As shown in FIG. 8, a plurality of fitting holes 15a-15k are formed in a fitting formation portion 15 on the right end of an increased frame 3. As shown in FIG. 9, a plurality of movable protrusions 12-12d, inserting protrusions 13-13g and cylindrical protrusions 16-16b are formed on the left end of the increased frame 3.

Thus, the protruding plates 19-19c can prevent the column base frame 1 with the opening prevention tool from rising due to the weight of the fresh concrete, even if the fresh concrete is poured into the column base frame 1 with the opening prevention tool.

Numeral 19d denotes through holes for passing the opening prevention tool 20 and the opening prevention band 21 therethrough. Left and right overhangs 20a, 20b of the opening prevention tool 20 or umbrella-shaped protrusions 21a-21b, 23a-23d of the opening prevention band 21 are inserted or pressed into the through holes 19d, 19d, 19d, 19d, . . . bored through the protruding plates 19-19c. The fitting protruding bars may be disposed on the front and rear surfaces or the front surfaces alone of the inserting protrusions 13-13g.

FIGS. 10 and 11 show other embodiment of the column base frame 1 with the opening prevention tool assembled by the use of the corner frames 2 and the increased frames 3. FIG. 10 is an elevational view of other embodiment of the column base frame with the opening prevention tool according to the present invention. FIG. 11 is a plan view of the column base frame with the opening prevention tool of this embodiment.

A column base frame 1a with the opening prevention tool shown in FIGS. 10 and 11 is a combination of the four corner frames 2 and the two increased frames 3. As shown in FIG. 11, the column base frame 1a with the opening prevention tool is slightly horizontally longer in the plan view.

As shown in FIGS. 10 and 11, the opening prevention tools 20 of the same shape and the same size can be also mounted in the horizontally longer column base frame 1a with the opening prevention tool. That is, even if the column base frame 1 is replaced by the horizontally longer column base frame 1a with the opening prevention tool, it is not necessary to manufacture the opening prevention tool 20 itself of new size.

FIG. 12 is a longitudinal cross sectional view taken along line A--A of FIGS. 10 and 11. As shown in FIG. 12, the opening prevention tools 20, 20, 20, 20 are mounted between the protruding plates 19, 19a, 19b, 19c and the protruding plates 19, 19a, 19b, 19c protruded from the increased frames 3, 3.

The column base frame 1a with the opening prevention tool of this embodiment, which is the combination of the corner frames 2 and the increased frames 3, is narrow in width in the upper portion thereof and is wide in width in the lower portion thereof. Therefore, the opening prevention tool 20 mounted between the protruding plates 19a and 19a must be slightly horizontally longer than the opening prevention tool 20 mounted between the protruding plates 19 and 19.

Also, the opening prevention tool 20 mounted between the protruding plates 19b and 19b must be slightly horizontally longer than the opening prevention tool 20 mounted between the protruding plates 19a and 19a.

However, in the column base frame 1a with the opening prevention tool of the present invention, the through holes 19d, 19d, 19d, 19d, . . . , which are formed in the protruding plates 19, 19a, 19b, 19c so as to pass the left and right overhangs 20a, 20b of the opening prevention tool 20 therethrough, are formed so that they may be more inside positioned as the protruding plates 19, 19a, 19b, 19c are more lowly positioned.

As described above, the more lowly the protruding plates 19, 19a, 19b, 19c are positioned, the more inside the through holes are formed. Therefore, the opening prevention tools 20 of the same shape and the same size can be mounted between the protruding plates 19, 19a, 19b, 19c and the protruding plates 19, 19a, 19b, 19c. Thus, there is no need for manufacturing the opening prevention tools 20 of different sizes.
